张飞vs关羽:虚心求教，高手们帮忙翻译一下吧

Supply chain impacts on a company are numerous and substantial. Supply chain costs can equal one-half, or more, of a company's revenues, while completing the demand generation-fulfillment cycle by linking a company and its products and services with customers. The supply chain enables a company to manufacture products at target cost levels, ensuring the right goods are received by the right customers in the right quantities at the right time.
Given a supply chain's integral role in executing a company's business strategy, it can do more than successfully fulfill demand generation needs. The role of the supply chain can be defined in five stages (see Figure 1.0). At the lowest levels of strategic value contribution, supply chain is purely execution focused- management develops plans to increase supply chain efficiency and cost performance. At higher levels, it is demanded that the supply chain demonstrate strategic value to the organization. The supply chain involves containment of operating costs, effective deployment of capital, risk management, and even revenue generation.
